My AirPods say “Made in Vietnam” but my serial number is correct

Hi I got AirPods Pro as a present recently bought in 2021, I have been buying Apple products for over 15 years, I can tell a fake. My Serial number checks out and I even bought AppleCare+ and the store told me that my AirPods case are fake but my earbuds are reall?? But how could I even have bought AppleCare?

can someone tell me for sure with 100% certainty if “made in Vietnam” AirPods are real or not?

I own 2 airpod pros and I have check the boxes and everything looks 100% I’m just perplexed…need help!
